I've built my game Galactic Impact is built in Ruby on Rails, anyone else here tried it? For folks who haven't, would you be interested in blog posts about ways to use it to build web games with it?
Granted, I've been using it a while as a web app technology, but I find I can generally build out entire new game systems in a day or two. It has stuff like user management available off the shelf, and it's a breeze to deploy to a PaaS host like Heroku. I'd be happy to share details if there's interest!
